How Medicare and Employer Insurance Work Together
When you have both Medicare and employer insurance, they coordinate benefits.
This determines:
Which plan pays first (primary payer)
Which plan pays second (secondary payer)
How much you pay out of pocket
This coordination is critical to understanding your coverage.
Who Pays First?
The order of payment depends largely on your employer size.
Employer with 20 or More Employees:
Employer insurance pays first
Medicare pays second
Employer with Fewer Than 20 Employees:
Medicare pays first
Employer insurance pays second
This distinction can significantly affect your costs and coverage.

You may consider enrolling if:
Your employer has fewer than 20 employees
Your coverage is limited
